I understand that the chances of this happening are slim to none, but I have a simple solution regarding the future of WWE.
Make Ryback and Reigns the last two men standing at Royal Rumble, and let the fans decide who wins based on crowd reactions for both.
The winner dethrones Lesnar at Mania. If it's Ryback, then turn Reigns heel for a post-Mania program. If it's Reigns, then put him against Rollins after Mania and/or a heel Ambrose and too bad for Ryback.
